From VOA Learning English, this is the Technology Report. LA Metro is the name of the Los Angeles public transportation system in California. It operates buses and trains in the Los Angeles area.

At LA Metro, some workers watch video screens for traffic delays or other signs of trouble. The system uses information from its cameras and sensor equipment. The workers will soon use data from a social media application called Waze. It uses reports from drivers who note real-time traffic conditions. The American technology company Google owns the application software, or app. Waze has partnered with cities around the world, from Rio de Janeiro to Jakarta, to see the traffic flow in populated areas. The California Department of Transportation communicates with drivers through message signs on roads, its highway mapping website, and social media sites like Twitter. A spokesman says traffic managers see millions of trips each day. But the system is old, he says. They are trying to inform travelers of the road conditions. Police departments are also using social media. But some police worry that apps like Waze may create a danger to officers because Waze can identify the positions of police officers. Charlie Beck is the police chief of Los Angeles. He expressed his concern about new media to Google in December 2014. A Google spokesman said they work with police to keep officers and citizens safer. Meanwhile, civil rights groups are using their social apps to urge citizens to keep watch on the police.
